A geometry in the set of solutions to ill-posed linear problems with box constraints: Applications to probabilities on discrete sets

Henryk Gzyl

When there are no constraints upon the solutions of the equation $\mathbf{A}\xi =\mathbf{y},$ where $\mathbf{A}$ is a $K\times N-$matrix, $\xi \in {\mathbb{R}}^N$ and $\mathb…
